Clustering with Semidefinite Programming and Fixed Point Iteration
Pedro Felzenszwalb, Caroline Klivans, Alice Paul
We introduce a novel method for clustering using a semidefinite programming (SDP) relaxation of the Max k-Cut problem. The approach is based on a new methodology for rounding the s…
Iterated Linear Optimization
Pedro Felzenszwalb, Caroline Klivans, Alice Paul
We introduce a fixed point iteration process built on optimization of a linear function over a compact domain. We prove the process always converges to a fixed point and explore th…
Spectral Image Segmentation with Global Appearance Modeling
Jeova F. S. Rocha Neto, Pedro F. Felzenszwalb
We introduce a new spectral method for image segmentation that incorporates long range relationships for global appearance modeling. The approach combines two different graphs, one…
